its not the peeling off thats hard....its removing the residue and glue the tint might leave behind if not done properly...

 

my hatch and two back corner windows are double layered its fine. since the tint i have dont come in less than 30%.

 

any pics?

 

you cant really tell its double layered. its just darker

 

people double tint all the time, guy at work has 2 layers of 5%, you cant see in or out, its definitely possible w/o damaging anything

 

yeah thats what i said haha

 

my buddy has it, looks fine

 

2 layers of 5%? thats crazy lol

 

Here's how I removed mine.....do at ur own risk....and in a very very well ventilated area

1. Things needed: Thick garbage bags cut up to slightly bigger than ur window
2. Ammonia (janitor-strength works best) in a spray bottle
3. Spray the ammonia on ur tints very carefully, avoid drips
4. cover the ammonia soaked window with a garbage bag and leave for 15/20mins
5. Get a plastic scraper and the tint should come right off

Some things to remember, Ammonia stinks, so leave ur doors/hatch/sunroof open to not get the smell in ur car. Wear gloves, if ur gonna use rags to avoid the drips, I suggest testing the rag out first, the rag may disintegrate depending on the concentration of ammonia, testing a small part of the tint may be a good idea too.

This method did not leave any glue behind and took me an hour or so to do.
